Amino Acids, Nucleosides and Nucleotides

Amino Acids

We offer Fmoc-protected unnatural amino acids for the synthesis of peptides for biological research and pharmaceutical development. By introducing conformational constraints, the peptides may have one or several of the following features: 1. enhancement of peptide backbone helicity for better target binding; 2. tunable hydrophobicity for desired cellular permeability and cytotoxicity; and 3. enhancement of peptide stability against proteolytic breakdown.

Nucleosides and Nucleoside Phosphoramidites

We offer nucleosides with modifications in both the nucleic acid base and the sugar component of the molecules. Nucleoside phosphoramidites are extremely useful chemical building blocks for the chemical synthesis of RNA-targeting drugs such as antisense oligonucleotides, aptamers, and siRNAs which have exhibited promises for treating diseases including muscular dystrophy, neuropathies, and macular degeneration.

Nucleotides

dNTP, NTP, and modified nucleotides have exhibited a wide range of applications in PCR, RT-PCR, cRNA synthesis, RCA, MDA, DNA labeling, and sequencing. dNTPs are chemical building blocks in the commercial manufacture of mRNA vaccines using in vitro transcription method.
